## Summary

DMEGC is a Chinese manufacturer founded in 1980 as part of the Hengdian Group conglomerate, with its solar division growing significantly from around 2009. Headquartered in Zhejiang Province, the company has scaled into one of China's larger vertically integrated solar producers, operating more than 20 specialized factories and six major production bases worldwide, including a 10 GW module base at Lianyungang. Annual module production capacity stands at roughly 21 GW, and full-year 2025 PV shipments reached approximately 24.9 GW - a year-on-year increase of over 45 percent. DMEGC appears on industry bankability tracking lists, reflecting its substantial institutional footprint. Techwise Solar Technology Co., Ltd. is a considerably smaller operation based in Rudong County, Nantong City, Jiangsu Province, with a staff of around 200 and an annual production capacity of approximately 1 GW. The company provides ODM and OEM manufacturing services to larger brands, which positions it as a contract supplier rather than a fully independent market leader.

DMEGC addresses a broad range of applications, from residential M10 rooftop modules to large utility-scale ground-mount projects - most notably a 940 MW supply agreement for a fishery-PV complementary development in eastern China. Its module lineup draws on half-cut monocrystalline and TOPCon cell technologies. Techwise Solar's catalog spans the Sun-Pursuit, Sun-Pursuit Pro, Sun-Pursuit Plus, and Micro Sun series, covering output ratings from compact residential panels to modules exceeding 600 W. The company works across PERC, TOPCon, and bifacial glass formats in multiple cell sizes, making it a technically versatile contract manufacturer suited to residential and commercial rooftop or small ground-mount projects.

For most international buyers, DMEGC is the more defensible default. Its multi-gigawatt scale, verifiable shipping volumes, and global manufacturing network offer stronger supply security and more credible long-term warranty backing. Techwise Solar may suit cost-sensitive buyers or integrators seeking customized ODM production runs, but its smaller size carries meaningfully higher counterparty risk over a 25-year panel lifetime. The two brands are not interchangeable: DMEGC occupies a substantially higher institutional tier.
